Astronomers have discovered the first Earth-sized planet that meets just the right qualities to potentially harbor life. With the help of the Kepler Space Telescope, they identified Kepler-186f, a ...

THE hunt for life in space has taken a step forward with the discovery of “Earth’s cousin” orbiting a distant star. The exoplanet dubbed Kepler-186f was first spotted by scientists using NASA’s Kepler ...

Kepler-186 and the Solar System: The diagram compares the planets of the inner solar system to Kepler-186, a five-planet system about 500 light-years from Earth in the constellation Cygnus. The five ...

NASA’s Kepler spacecraft has discovered a “cousin” of Earth 1,400 light-years away. The exoplanet Kepler 452b orbits a sunlike star at about the same distance as Earth orbits the sun, scientists ...
